Test conditions and notes11

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
2. Please refer to "DRIVING METHODS OF LED MODULE".
3. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
4. Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to increase of the set up time.
5. The driver is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
6. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 80℃ or less.
7. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com.
8. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
9. For any application note and IP water proof function installation caution, please refer our user manual before using. https://www.meanwell.com/Upload/PDF/LED_EN.pdf
10. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED power supply can only be used behind a switch without permanently connected to the mains.
11. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

Is the ELG-240-C1750DA compatible with DALI building automation systems?

Yes. The DA suffix indicates a built-in DALI (Digital Addressable Lighting Interface) dimming input. The driver can be addressed and dimmed directly from a DALI controller on a shared two-wire bus, enabling integration with building management systems and scene-based lighting control in commercial or institutional LED downlight installations.

Can the ELG-240-C1750DA be used in outdoor LED signage where rain exposure is a concern?

Yes. The ELG-240-C series is rated IP65 or IP67, sealed against dust and water, making the driver suitable for outdoor sign enclosures exposed to rain. Its -40°C to +85°C case temperature (Tcase) rating also supports outdoor deployment in most climates.

What LED load voltage range works with this driver?

The ELG-240-C1750DA is a constant current driver delivering 1750mA; its output voltage self-adjusts between 69V and 137V to maintain that current. The number of LEDs that can be connected in series depends on each LED's forward voltage, provided the total string voltage falls within 69–137V.

Is this driver suitable for powering high-power LED arrays in a sports or industrial facility?

Yes. At 239.75W and 1750mA with IP65/IP67 sealing and a broad operating temperature range, the ELG-240-C1750DA can drive the high-power LED arrays found in sports hall floodlights or industrial high-bay luminaires, particularly where DALI dimming is required for energy management or occupancy-based control.

How does the DALI variant compare to the standard ELG-240-C1750 without a dimming interface?

Both the ELG-240-C1750 and ELG-240-C1750DA share the same power (239.75W), current (1750mA), CC voltage range (69–137V) and safety certifications. The key difference is that the DA variant includes a DALI dimming input (IEC62386-101/102) for digital bus control, whereas the base model has no dimming capability.

Can I install the ELG-240-C1750DA in a humid or tropical outdoor environment?

Yes, with care. The series' IP65/IP67 rating protects against moisture ingress, and the driver is rated for a case temperature (Tcase) of -40°C to +85°C; at high ambient temperatures the output load must be derated per the sheet's output load vs temperature curve. It is approved to UL8750, CSA C22.2 No. 250.13-12, EN/AS/NZS 61347, GB/T19510, KC and EAC standards for international markets.
